METALLIC FASTENER FOR ATTACHING BUTTONS TO SHOES, $4.6.

SPECIFICATION forming part of Letters Patent No. 546,349, dated September 17, 1895.

Application filed February 17, 1893- Serial No. 462,683- (No model.)

To ctZZ whom it may concern:

Be it known that Lisa J. SAUNDERS, a citizen of the United States, and aresident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Metallic Fasteners for Attaching Buttons to Shoes or other Materials, of which the following is a specification.

My invention relates to improvements in metallic fastenings made from flat metallic strips for attaching buttons to shoes and other materials, and has for its object the strength ening of such fastenings and their better adaptation for use in connection with buttonfastening machines.

Such metallic fastenings are staple-like in shape, the head thereof being a short arch forming the bearing for the button-eye when in, use, and at the neck or foot of the arch the bow has shoulders which receive the impact of the driver by which the legs are forced into the shoe, to be clinched on the other side. These fastenings are most commonly made from ordinary wire. proved fastening from a flat strip of metal of a proper width for the arch or head, as well as for the legs or prongs.

The drawings hereto annexed show a fastoner made of a flat strip of metal embodying my invention.

Figure 1 is afront elevation. Fig. 2 is a top view; Fig. 3, a side view, as of Fig. 1. Fig. l is a cross-section of the arch or head, and Fig. 5 is a cross-section of the neck.

A indicates the arch or head; B, the shoulders; O, the neck, and D the legs.

As hitherto made, such fastenings have developed a weaknessin the neck near its junction with the shoulders, causing the neck to kink and the head to lop over, thus endangering the integrity of the fastening. To

prevent this, I have the neck formed with Instead, I make my imcorrugations in cross-section, as indicated in Fig. 5. Such corrugation is preferably made by forming indentations e in the neck C, as indicated by dotted lines in Fig. 1, resulting in a protuberance f on the under side. lhis indentation not only corrngates the fastener at its weakest point, and thereby imparts needed strength, but the resulting protuberance improves the form of the neck in crosssection, and by preserving the proper curvature of the neck facilitates the threading of the fastener into the button-eye in the operation of attaching buttons to shoes by the machines used for that purpose. It is also of advantage in handling the fasteners in such machines to have the fastener about the same diamensions asto width throughout. I therefore leave the arch Aof the same width as the remainder, as indicated in Fig. 3; but to conform the same approximately to the interior curve of the button-eye the arch is preferably rounded on the under side, as indicated in cross-section in Fig. 4.

Metallic fasteners made as above described have the advantages of increased strength and of adaptability for mechanical manipulation in button-fastening machines above any similar fastening now known.

I claim as my invention and desire to secure by Letters Patent- The metallic fastenerdescribed combining the following elements namely, a hat metal strip having the arch A the inclined portions G provided with the corrugations f, and shoulders B substantially as specified.
